BURTON W. ROBBINS, OF ST. PETERSBURG, FLORIDA.

AUTOMATIC WAGON-BRAKE.

Specification of Letters Patent.

Patented Nov. 14, 19.16.

Application filed January 14, 1916. Serial-No. 72,088.

To all whom it may concern:

Be it known that I, BURTON W. ROBBINS, a citizen of the United States,residing at St. Petersburg, in the county of Pinellas and State ofFlorida, have invented certain new and useful Improvements in AutomaticlVagon-Brakes; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to that type of wagon brakes, which areautomatically applied by the back pressure of the horse or horses,especially when the vehicle is going down hill, and an obiect of theinvention is to improve this construction of brake so that the same willbe of simple construction,

cheap to manufacture, efiicient in operation and of such constructionthat the brake can be heldin inoperative position when it is desired toback the wagon.

Other objects will appear and be better understood from thatembodimentof my invention of which the following is a specification,reference being had to the accompanying drawings forming a part thereof,in which:

Figure 1 is a bottom plan view of the running gear of a wagon, showingmy improved brake applied thereto. Fig. '21s adetail side view of theforward end of the wagon tongue, showing an improved tip appliedthereto, and showing the ordinary neck yoke" ring in moved position onthe tongue. Fig. 3 is a detail side view of the forward end of thetongue and showing the position of the neck yoke ring, when the vehicleis being hacked, and Fig. at is a forward end view of the wagon tongueand tip.

Referring to the drawings in detail, the numerals l and 2 designate,respectively, the front and rear axle of the wagon and 3 the reach forconnecting the front and rear axles. The rear hounds of the wagon areshown by the numerals 44.-, and extending across the inner ends of thehounds 4: and the rear end of the reach 3 is a transversely extendingbar 5. Extending parallel with the reach pole 3 and on opposite sidesthereof is a pair of cylindrical shaped rods 6, the rear ends of therods having connection with eye-bolts 7 carried by the rear axle 2, andthe forward ends of the rods 6 arefiattened, as shown at 8, and areextended beneath the lower side of the rod 5 and secured thereto bymeans of the fastening elements 9. A pair of spaced brake bars 10 arearranged in parallelism with the transversely extending bar 5 and eachhas its pivotal connection, at a. point approximately intermediate itsends with the forward terminal of the adjacent rod 6, by means of thepivot pin 11, and the outer end of each of the brake bars I0 isproprovided with a brake shoe 12, which is adapted, when the brake rodis moved in one direction, to'engage the adjacent wheel of the wagon.

Extending beneath the lower side of the reach pole 3, is a cable 12,which is pref erably formed of wire sections detachably connected toeach other by means of snap hooks and links, the rearmost wire sectionbeing secured to the terminal of the stem of a Y-shaped member 13, thebranches or sides of the Y-shaped member being extended in the directionof the brake bars 10 and secured thereto by means of connecting wires14, as shown in Fig.1 of the drawing. Located in rear of the brake bars10 is asecond Y-shaped member 15, the sides or branches of which haveconnection with the inner ends of the brake barslO by means of wires,and the said (shaped member has its stein connected,---by means of aconnecting member 16, to one terminal of a horizontally disposedcontractile" spring 17, the opposite end of the spring having connection'with an eye 18 formed on the shank of a hook 19, the said hook havingits bill v2O received by an eyebolt 21 secured to the inner side of therear axle 2 of the wagon. The cable 12 is slidably extended throughguides 22 carried by the lower side of the reach pole 3, and has itsforward end extending through similar guides formed on the lower side ofthe tongue 23 of the the tongue 23, adjacent the forward end thereqf.When the brake bars 10 are in inoperative position, as shown in Fig. 1,the spring 17 will be contracted and the flexible element 12 movedrearwardly so as to hold the lever 29 at the forward end of the 7 slotinthe tongue.

In Figs. Qand 3 ofthe drawings is shown a neck yoke ring 32 of usualconstruction and when the wagon is moved forwardly the ring will belocatedlin rear of the depending arms 27, and has its upper side locatedadj acent the lever 29. When the wagon is going down a hill and backwardpull is caused by the horses, the ring 32 will be moved into engagementwith the lever 29 and rock the upper end thereof rearwardly, causing thelower end of the lever to move forwardly andexert a forward pull on thecable 12 so as to rock the brake bars 10 to effect engage ment betweenthe brake shoes 12 and the adjacent rear wheels of the wagon. lVhen thebrake bars 10 are rocked to efi'ectengage ment of the brake shoes withthe rear, wheels, the springl? will be expanded, so that when therearward pull is released, the spring 17 will return the operating leverand the brake bars 10 to their normal position; When it is desiredtoback the wagonwithout applying the brakes, the neck yoke ring 32 ismoved forwardly by hand and the lower side thereof positioned againstthe forward sides of the arms 27, so that when rearward pull is exertedon the ring, the same will be held against rearward movement so as notto ef- 7 feet operation of the lever 29;

Copies of this patent may be obtained for Having thus described myinvention what 7 I claim as new is:

l. The combination with the rear axle and the reach pole of a wagon, ofa bar extending transversely of the reach pole adjacent the rear endthereof and secured thereto and arranged in spaced relation with therear axle, a pair of rods arranged on opposite sides of the reach poleand parallel therewith, and having their rear ends connected to theaxles and their forward ends extended beneath the transverse bar andsecured thereto and terminally extending beyond the transverse bar,brake bars pivoted to the extended terminals of the rods, means foroperating the brakebars, and means connected to the brake bars and therear axles for returning the brake bars tonormal inoperative position.

2. In brake operating mechanism for a wagon, the combination with awagon tongue and a bra he operating cable, and an operating levercarried by the tongue and having connection with the cable, of aU-shaped tip associated with the tongue and having the bight portionthereof located in advance of the lever and the tongue and having thesides thereof extending along the sides of the tongue, downwardly andforwardly convergin arms extending from the sides of the tip, means forconnecting the arms to each other, the said arms being arranged inspaced relation with the bight portion of the tip and located in advanceof the tongue, for the purpose specified. v V

In testimony whereof I aflix my signature in presence of two witnesses.
